Heavy El Niño rains have spurred the growth of poisonous mushrooms in California, which are potentially dangerous for pets playing outside.
North Atlantic right whales were given some more elbow room in critical foraging and breeding habitats off the coast of New England, Florida and South California. These new designations were made by the National Oceanic and Atmospheric Administration in hopes of further aiding the whales' recovery.
National Park Service biologists recently discovered two mountain lion kittens in the Santa Monica Mountains in California. The pair's mother is thought to be a well-tracked mountain lion designated as P-19, but DNA testing is underway to confirm who their father is. Nonetheless, researchers say this successful birth highlights the habitat quality of the Santa Monica Mountains.
Pierce's disease has been wreaking havoc on Californian grapevines since the 1890s. But researchers have identified an enzyme that helps explain the disease's extensive damage and could lead to bettter protection of the vines.
Thanks to California’s ongoing drought, nearly 888 million trees have experienced drought-related stress since 2011. Of these trees, 58 million have reached dangerous water-loss thresholds, researchers say.
Californian sea lions exposed to lethal doses of an algal toxin known as domoic acid are suffering from brain damage and memory loss.
Using an ear mite treatment commonly used to kills those found in cats and dogs, researchers from the University of California Davis have developed a way to reduce the presence of tumors in the ears of endangered foxes living on California's Santa Catalina Island.
After the outdoors retailer REI declared in October that the company's 143 stores would close for Black Friday, municipalities and states around the country responded with free, discounted, and ranger-led events in nature for the day after Thanksgiving.

Illegal marijuana farms in forested areas of California are threatening the survival of a rare weasel-like species known as fishers.
Oil-based pesticides are more effective than water-based alternatives when it comes to killing brown widow spider at the source: their egg sacs.
Humboldt County, California isn't just about cannibis, and Humboldt Glacier (too) has a really serious namesake who (in the early 1800s) originated the ideas we have now about nature. A new book is about this natural historian, scientist and world explorer who influenced Darwin, Thoreau, Emerson, Goethe and people in nations around the world.
While it has long been known that eastern California's Mono Lake and Mono Craters were set above a volcanic system, new 3D images of the massive magma chambers beneath will help scientists make predictions for the next eruption, a study says.
Even though plants first emerged on Earth 400 million years ago, it was not until approximately 80 million years later that wildfires began ripping through forests and grasslands like they do today in California. This could explain why plants were able to diversify the way they did.
